Bytecode is a special type of code that the Java compiler creates from your Java program. It’s not directly understood by the computer’s processor like machine code, but instead runs on the Java Virtual Machine (JVM) . This makes it platform-independent , meaning the same bytecode can run on any device with a JVM — whether it’s Windows, Mac, or Linux.

In contrast, object code  is the machine-level code generated from languages like C or C++, and it’s specific to the computer’s hardware and operating system. So, bytecode helps Java achieve its famous "Write Once, Run Anywhere" feature, while object code is tied to one particular platform.
